I wrote this book to provide a clear, actionable, and accessible synthesis of today’s most advanced language models. My goal is to empower professionals—whether in digital, training, communication, or strategy—with a solid understanding of generative AI and how to turn it into a real operational asset.

I compare the leading models (ChatGPT, Gemini, Claude, Perplexity, Mistral), explain their inner workings, limitations, and, most importantly, how they can be applied to real business use cases. The book is grounded in real-world examples, prompt benchmarks, and insights from over 1,000 people I’ve trained in AI. It also includes techniques for prompt optimization, advanced use cases, and guidance on how to implement generative AI effectively in organizations.

This book reflects my approach: practical and impact-driven.
